Insights

Director received deferred stock units payable at termination, increasing direct share count.

The filing shows a routine, non-cash compensation event: 817.5105 deferred stock units awarded under the company's Deferred Compensation Plan and recorded as an acquisition on 10/01/2025. These units vest/payable in stock only upon termination and carry no exercise or expiration date, so they represent future-controlled equity rather than immediate stock transfer.

This change raises the reporting director's direct beneficial ownership to 82,199.5392 shares, a disclosure relevant for ownership concentration and insider alignment with shareholders.

Compensation granted in deferred stock units aligns pay with long-term ownership and deferral rules.

The transaction is described as compensation under the Deferred Compensation Plan with payment in stock upon termination, indicating a deferred equity-based payout rather than an option or cash award. No price or exercise terms apply, and the reported per-unit value shown ($94.8) appears as a reference to an underlying share value at reporting, not an exercised price.

This is a standard mechanism to retain executives/directors and link pay to company equity over time.
